Available Online: https://sciforum.net/conference/ecsoc-22. Published: 14 November 2018 Abstract: Medicinal plants are in rich source of antimicrobial agents. The present study was carried out to evaluate the antimicrobial effect of plants from the same species as Brassica oleceracea namely, white cabbage and red cabbage. The preliminary phytochemical analysis was tested by using a different extract of these plants for the presence of various secondary metabolites like alkaloids, flavonoids, tannins, saponins, terpenoids, glycosides, steroids, carbohydrates, and amino acids. The in vitro antimicrobial activity was screened against clinical isolates viz gram positive bacteria Staphylococcus aureus, Streptococcus pyogenes, gram negative bacteria Escherichia coli, Pseudomonas aeruginosa. Extracts found significant inhibition against all the pathogens. Keywords: plant extract; phytochemicals; antibacterial activity; antifungal activity 1. Introduction Despite great progress in the development of medicines, infectious diseases caused by bacteria, fungi, viruses and parasites are still a major threat to public health. The impact is mainly observed in developing countries due to relative unavailability of medicines and the emergence of widespread drug resistance [1].
